These wheels are solid and seem like they’ll hold up well—always the real test when cutting hard materials, especially with diamond blades. At just $13 for a full set, they’re a bargain compared to single blades that can cost $20 or more.Cutting glass is always tricky, with so many variables depending on the type and thickness. These wheels get the job done in some cases, but results are inconsistent. They performed great on ceramic tile, delivering fast, clean cuts. But with glass, it was a mixed bag—some cuts were fine, while others left rough or chipped edges. Even with precautions to prevent cracking, some pieces still shattered.I’m experimenting with ways to improve longevity and performance. I have a tile saw with a water-cooled diamond blade, and I’m considering putting on one of these blades and trying to cut glass. If you don’t have a tile saw, setting up a cooling system—maybe using a spray bottle, a DIY drip setup, or even IV bags for a steady water flow. Keeping your grinder straight, and doing a slow steady cut should help give better results.Bottom line? They’re great for some materials but unreliable for glass. If you go in with realistic expectations and a little ingenuity, they’re definitely worth the price.

These are solid wheels that may actually last a little while. That's the test for cutting hard materials, how well it survives, particularly diamond. I think these will do well enough to justify the crazy low price of ~$13. Some of these things go for $20 just for one.

Like the headline, there are many variables with cutting glass for the types of glass and situations. Seems to work though.

Horrible for cutting glass no matter what you put on da glass to keep from chipping or cracking does not work so rate as garbage because they went right into the trash can!thank you.

I used these for trimming pots to size. Worked great, did fast, clean cuts.

These definitely cut through the glass. They completely destroyed the edged though. They also cut a very thick cut. It's a .25" wide cut.

Have made a random mosaic tabletop with miscellaneous broken tiles. Am interested to see what I can do with glass shapes cut from colored glass bottles. My tile saw I use to cut porcelain uses a water-cooled diamond blade. Been awhile since I used it. Need to look at it and see if I can use the water-cooling pump separately or run the spray without activating the saw. If not, should be fairly easy to find a way to clamp my grinder to make it function as a stationary tool and bring the glass to it. If I can set the switch to always on, I might be able to just cool the blade using a water-filled spray bottle. Another solution might be to rig a quart or gallon plastic container as a drip or get some hospital IV drip bags and just let gravity do the work of constantly cooling the cutting blade. Would be easy to restrict the flow rate of liquid through a small plastic tube. These blades are inexpensive but why use them as one-off when, with a little ingenuity, you could use them multiple times before recycling them as scrap metal. They're probably made from recycled steel but look to be good quality for a set of blades so inexpensive.
